On a widely held characterization, triadic joint attention is the capacity to perceptually attend to an object or event together with another subject. In the last four decades, research in developmental psychology has provided increasing evidence of the crucial role that this capacity plays in socio-cognitive development, early language acquisition, and the development of perspective-taking. Yet, there is a striking discrepancy between the general agreement that joint attention is critical in various domains, and the lack of theoretical consensus on how (...) to account for it. This paper pursues three interrelated aims: (i) it examines the contrast between reductive and non-reductive views of (triadic) joint attention, by bringing into focus the notion of recursive mindreading; (ii) it assembles, advances, and discusses a number of arguments against reductive views; (iii) finally, in dialogue with some prominent non-reductive views, it outlines the case for a non-reductive view that gives pride of place to the idea that co-attenders relate to one another as a ‘you’.

Den Philosophen und Theologen Friedrich Schleiermacher und den dänischen Philosophen, Mineralogen und Theologen Henrik Steffens verband nicht nur eine enge Freundschaft, sondern sie verstanden sich – kurz nacheinander 1804 an die Universität Halle berufen – auch als wissenschaftliches Pendant. Grundlegend für den gefühlten Gleichklang beider Köpfe ist der romantische Gedanke progressiver Universalität, der auf der Suche nach einer angemessenen wissenschaftlichen Methodik gleichermaßen die Forderung nach System und Antisystem, System und seine Subversion generiert. Trotz dieser häufig konstatierten wissenschaftlichen Entsprechung beider Denker (...) ist ihr systematisches Verhältnis bis dato in der Forschung kaum bedacht und ebenso Desiderat wie die philosophische Literatur zu Steffens Werk überhaupt. Die Beiträge des Bandes gehen biographischen Spuren nach, thematisieren die Einheit des Wissens im Spannungsverhältnis von System und Subversion, untersuchen das Wechselverhältnis von Ethik und Physik, Naturphilosophie und Naturwissenschaft und fragen auch nach den im Verlauf ihrer Freundschaft zunehmenden Differenzen im Denken beider Philosophen, die sich nicht zuletzt in ihren theologischen und kirchenpolitischen Schriften manifestieren.

Powers of Horror is an excellent introduction to an aspect of contemporary French literature which has been allowed to become somewhat neglected in the current emphasis on para-philosophical modes of discourse.".

Given any finite graph, which transitive graphs approximate it most closely and how fast can we find them? The answer to this question depends on the concept of “closest approximation” involved. In [8,9] a qualitative concept of best approximation is formulated. Roughly, a qualitatively best transitive approximation of a graph is a transitive graph which cannot be “improved” without also going against the original graph. A quantitative concept of best approximation goes back at least to [10]. A quantitatively best transitive (...) approximation is a transitive graph that makes the minimal number of mistakes against the original graph. In other words, the sum of the edges that are removed from and are added to the original graph is minimal. (shrink)

Eric Davidson was a legend both in his science and his personality. He inspired and challenged a new generation of developmental biologists and I was lucky to be one of them. He changed the way we think about biological interactions by synthesizing a large scale, almost incomprehensible set of data into a causal model of a gene regulatory network. While his death leaves a big hole in our lives, his contribution to the conceptualization of regulatory biology will inspire developmental and (...) evolutionary biologists for decades to come.

Para explorar las diferencias significativas entre estos dos pensadores, la primera parte de este articulo considerará sus ideas ontológicas. Comenzando con su preocupación común por la multiplicidad, exploraremos el movimiento fundacional de Deleuze hacia diferentes tipos de multiplicidad. La crítica de Badiou a este enfoque estará relacionada con su defensa de los recursos abstractos de la teoría de conjuntos en oposición a las síntesis concretas con las que Deleuze busca comenzar. La segunda parte de este documento explorará las consecuencias de (...) los compromisos ontológicos de Deleuze cuando se trata de la ética del acontecimiento exigido por Badiou. El compromiso de Deleuze con el estoicismo proporcionará el escenario para su explicación de cómo ocurren los acontecimientos y representa una fuente de pensamiento y actividad. En la tercera y última parte se buscará evaluar la explicación de Deleuze sobre el papel de los acontecimientos en situaciones particulares y en las actividades de los sujetos que responden a estos. Esto nos permitirá sacar conclusiones sobre la crítica de Badiou a Deleuze y la capacidad de Deleuze para resistir estas críticas. Argumentaré que Deleuze comparte con Badiou la preocupación de mantener una visión clara del tema como una figura comprometida en la búsqueda de proyectos nuevos e inauditos que responden al llamado de los acontecimientos.

[ES]Una historia de la ontología que pretenda dar cuenta de su acontecer de manera integral y equilibrada, ha de considerar tanto los aspectos historiográficos y filosóficos de sus fuentes así como los relativos a su contexto socio-cultural y necesariamente en relación con los de la metafísica, pues sus historias están indisolublemente ligadas, aunque ello no significa que necesariamente sean las mismas. En este trabajo, se intenta de manera elemental y mínima bosquejar dichas consideraciones, a través de una breve revisión historiográfica (...) de distintas nociones y hechos que puedan configurar una base sólida para la constitución de la historia de la ontología e interpretación de su significado y naturaleza. [EN] A history of ontology that pretends to be an integral and well-balanced account of its development, must considerer the historiographical and philosophical aspects of its sources, as well as the relation with its socio-cultural context, and necessarily, the relation with the same aspects of Metaphysics, as both histories are inextricably related, without necessarily being the same. In this work, it is intended, in a minimal way, to outline such considerations, trough a brief historiographic revision of the distinctive facts and notions that can configure a solid ground for the constitution of the history of ontology and the interpretation of its significance and nature.

§1. Introduction. This paper deals with aspects of my doctoral dissertation which contributed to the early development of model theory. What was of use to later workers was less the results of my thesis, than the method by which I proved the completeness of first-order logic—a result established by Kurt Gödel in his doctoral thesis 18 years before.The ideas that fed my discovery of this proof were mostly those I found in the teachings and writings of Alonzo Church. This may (...) seem curious, as his work in logic, and his teaching, gave great emphasis to the constructive character of mathematical logic, while the model theory to which I contributed is filled with theorems about very large classes of mathematical structures, whose proofs often by-pass constructive methods.Another curious thing about my discovery of a new proof of Gödel's completeness theorem, is that it arrived in the midst of my efforts to prove an entirely different result. Such “accidental” discoveries arise in many parts of scientific work. Perhaps there are regularities in the conditions under which such “accidents” occur which would interest some historians, so I shall try to describe in some detail the accident which befell me.A mathematical discovery is an idea, or a complex of ideas, which have been found and set forth under certain circumstances. The process of discovery consists in selecting certain input ideas and somehow combining and transforming them to produce the new output ideas. The process that produces a particular discovery may thus be represented by a diagram such as one sees in many parts of science; a “black box” with lines coming in from the left to represent the input ideas, and lines going out to the right representing the output. To describe that discovery one must explain what occurs inside the box, i.e., how the outputs were obtained from the inputs. (shrink)

This paper focuses on the conceptual relationship between rationality and progress as applied to scientific development. The concept of methodology is used in the sense of a model of scientific change. It is argued, as against e.g. recent discussion by Larry Laudan, that progress implies rationality. The notion of rationality useful for this conception of scientific development includes instrumental rationality, butalso the idea of rational paradigm-shift, which is analysed in terms of changes of conceptual frameworks. The key idea is the (...) posibility of a rational reconstruction of series of conceptual frameworks, where the shift from one framework to its successor may be reconstructed as rational in the sense of there being reasons in the successor for accepting the change, and thus the whole series being rational.

About a month after his 83rd birthday Raphael Robinson was almost wholly incapacitated by a massive stroke, and 8 weeks later, on January 27, 1995, he died of ensuing complications. Mathematics was his life. He was always working on problems—those brought to him in journals or by colleagues, and others that he invented. Just three days before his death he received word that a paper of his, originating in a published problem, was accepted for publication. His 64 publications spanned a (...) full 6 decades, and included significant papers on number theory, combinatorics, complex analysis, and geometry, in addition to logic and set theory.Robinson was born on November 2, 1911, in National City, California. He came to Berkeley to study mathematics, obtaining an A.B. in 1932, an M.A. in 1933, and his Ph.D. in December, 1934. His dissertation was in complex analysis. He took 12 graduate courses in a variety of fields, but not one was close to logic or set theory—which was later the setting of about a quarter of his publications.After completing his studies Robinson served as Instructor for two years at Brown University, then returned for good to Berkeley in 1937, reaching the rank of full Professor in 1949. He taught a great variety of courses and was known as an excellent teacher, but was most interested in problemsolving and research and in 1972, at age 61, he elected early retirement, at considerable financial sacrifice, in order to concentrate on these pursuits.

L'A. propose ici une lecture de la Bible, philosophique et en recherche de la sagesse. Il illustre cela en recherchant dans l'étude de la Bible ce qu'il appelle le rêve humaniste qui revient sans cesse de la société rationnelle. Parce que la Bible enseigne, la plupart du temps, non par argumentation, mais par récits, il propose de s'arrêter sur la première histoire concernant ce thème, celle de la ville et de la tour de Babel, racontée dans le livre de la (...)

In this paper, I critically examine the monist interpretation of the logic-as-model view that Erik Stei puts forth in Logical Pluralism and Logical Consequence. I will argue that, in addition to the three dimensions presented in the book, there is a fourth dimension on which pluralism in logic could arise, namely epistemological pluralism. An example of such a form of pluralism is model pluralism, being the idea that we need multiple models to fully account for the subject matter of logic. (...) Such a form of pluralism is well-recognized and widely acknowledged in (model-based) science. I argue that if we endorse the logic-as-model view, then we should also recognize such a form of model pluralism in logic. While model pluralism is consistent with metaphysical monism — the idea that there is ultimately only one extra-systemic logical consequence relation — it does put pressure on the idea that there is one uniquely best model that fully captures that phenomenon.
